996 GT3 Mark II IPD 82mm Plenum

As with all GT3's, power improvements are very difficult to develop because of Porsche's fantastic out-of-the-box design and development on these performance minded machines.

The GT3 engine was specifically developed to deliver power where it's needed on the track, way up high in the rev range. The IPD Plenum compliments that power by delivering additional horsepower throughout the entire power band, especially in the mid range where it's most needed.
